Non-Lubricated Plug Valve vs Lubricated Plug Valve: Which is Best for Your Application?
Compare non-lubricated and lubricated plug valves by sealing design, operating torque, pressure and temperature capability, maintenance, contamination risk, and application. Non-lubricated plug valves suit cleaner, low- to medium-pressure services where lubricant contamination is undesirable, while lubricated plug valves provide smoother operation and stronger sealing for demanding high-pressure and high-temperature industrial systems.
